Psyxologos Posted January 21, 2015 Report Share Posted January 21, 2015 I was out shooting rabbits (and some paper targets afterwards) yesterday. It was crisp at -2 but a very enjoyable sunny afternoon. After I managed a couple of rabbits (there were not many around) I set up a couple of targets at 100 meters for some plinking fun. Shooting went well, I am still getting to know my CZ after I have put about 300 rounds through it. One thing I noticed is that there was a bit of smoke (remaining from the shot just fired) coming from the moderator after I closed the bolt for another shot. So I started blowing lightly down the chamber before I chambered a new round, and lo and behold plenty of smoke came out the front. Now, I did not notice any difference on accuracy depending on whether I 'de smoked' the barrel or not, but it got me thinking. Should the presence of quite a bit of smoke in the barrel from the previous shot not alter the ballistics and/or the trajectory of the next shot? I guess if there is smoke in the barrel already, the compression is different, or this is the theory. Am I missing something? Quote Link to comment Share on other sites More sharing options...
Torbruk Posted January 21, 2015 Report Share Posted January 21, 2015 Just bottle it and send it to me. I love the smell! Serious answer. I don't think it will make much difference. Have you ever seen the forces stop to blow smoke out of the barrel between rounds on a magazine fed machine gun? Quote Link to comment Share on other sites More sharing options...
Flynn Posted January 21, 2015 Report Share Posted January 21, 2015 The pressure in the barrel after a shot always falls back to ambient air-pressure. Doesn't matter if it's got rain, smoke or fog in there, it's going to be roughly 1 bar. Your next shot wont be affected by ambient pressure by any measurable degree unless it fluctuates a lot. "A lot" is subjective but if the sun comes up and you get a few degrees change in temperature, or you climb/fall a few hundred feet then you'll see a change in POI but realistically, that's not likely to happen.

Torbruk Posted January 21, 2015 Report Share Posted January 21, 2015 Added to say. Your breathing, and control of such will have FAR more influence on the accuracy of your follow on shot than a puff of smoke in the barrel. That and your smoothness of trigger pull.

Psyxologos Posted January 22, 2015 Author Report Share Posted January 22, 2015 Thanks for the answers.They make sense. As I said I did not notice any difference in accuracy, but my question was purely academic. Quote Link to comment Share on other sites More sharing options...
Underdog Posted January 22, 2015 Report Share Posted January 22, 2015 Blowing warm moist air will cause condensation. Shooting in this cold any large amount will also cause condensation to form and collect near the threads and muzzle. Remove mod to be sure! U.

I always remove the mod when I get home and clean the rifles, if this is what you were referring to. Or did you mean remove the mod when in the field?
